** Motor type definitions:
Shaded Pole:  A shaded-pole motor is a small, self-starting motor in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole. Most greenhouse exhaust fans have a shaded pole motor.
PSC:  Permanent split capacitor (PSC) motors use a capacitor in one of the windings to increase the current lag between the two windings to make the rotor turn.
Universal:  The universal motor is a type of electric motor that can operate on either AC or DC power.  It uses an electromagnet as its stator to create its magnetic field. If a commutator and brushes are present, the motor can be classified as either a DC or an AC motor (Universal motor).
